The single hydraulic prop is most used as support equipment in coal mines. The underground coal mine is a relatively dangerous place, so use and manage it with care. Let's take a look at the management methods of single hydraulic prop compiled by experienced staff.
1. First, train a full-time team for the use, handling, management, and maintenance of hydraulic prop, establish a management responsibility system and acceptance system, and improve management procedures. Count and verify the quantity carefully. Those who cause serious damage or loss during use or handling shall be investigated for responsibility and punished accordingly.
2. In the course of use, if one of the following situations is encountered, the hydraulic acrow props must be lifted and repaired immediately: the hydraulic prop automatically unloads the column; the hydraulic acrow props does not fall after the live column is unloaded; the unloading mechanism fails; the hydraulic acrow props body is obviously deformed or damaged ; The living hydraulic acrow props of the pillar shrinks to the end, forming the support of the dead single hydraulic prop.
3. The single hydraulic prop used on the working face must be in good condition, and the intact rate of the current pillars shall not be less than 90%.
4. The hydraulic prop has been used in the underground for more than 8 months, and the well is lifted and repaired; once the single hydraulic prop is damaged or temporarily not used in the underground, it should be transported to the well for maintenance and repair in time to increase the turnover rate and reduce the production cost.
5. All the hydraulic prop transported to the well must be dismantled and washed, repaired to remove coal dust, etc., and the corroded pillars shall be galvanized and phosphated: after long-term use of the three-purpose valve, the sealing ring is aging and the leakage is serious. To be disassembled and inspected and replace the sealing ring.
6. Perform high and low voltage and voltage stabilization tests on the hydraulic prop after maintenance, and then they can be put into use only after passing the acceptance.
7. In order to ensure the normal production of the working face, there must be spare hydraulic prop with more than 10% of the total in-plane use pillars near the working face, and they must be neatly erected in a safe, dry and clean place near the working face: the working face has a relatively high change in height. Large, correspondingly increase the pillar reserves and pillar specifications.
8. Single hydraulic prop that are idle on the ground and to be repaired shall not be stored in the open air. They shall be classified and stored in the maintenance workshop or warehouse with dry air and room temperature above 0cI=.
9. When the hydraulic acrow props is scrapped, it shall be carried out in accordance with the maintenance procedures of the single hydraulic prop.
